For each CNx bit:
0 = use RTS to enable transmitter or transmitter always on as defined by BA + 4 register CNx bit
1 = Use TxD to enable transmitter, transmitter data is tied low
For each Txd+/-CNx bit if corresponding CNx bit is 1:
0 = Use TxD to enable transmitter
1 = Use inverted TxD to enable transmitter
